Compu Pool CPSC Series Manual 4
3.1.9 When replacing the cell, only use replacement cells having a label that clearly
states that it is a replacement cell for this model.
3.1.10 Follow all aspects of the local and National Electrical Code(s) when installing the
CPSC Series Chlorine Generator.
3.1.11 For proper sanitation, spas must be completely drained periodically. The number of
days between COMPLETE SPA DRAINAGE is equal to the volume of the spa
water in gallons, divided by 10 times the maximum number of daily spa users.
Refill spa with water and repeat DIRECTIONS OF USE of this device.
3.2 Health and Hyperthermia warnings for spa devices
3.2.1 People with a medical condition should consult a physician before entering pool or
spa water.
3.2.2 Maximum spa water usage temperature is 104°F. Bathing time in spa water at
104°F should not exceed 15 minutes.
4.0 THE CHEMISTRY INVOLVED
4.1.1 The CPSC Series Chlorine Generator by electrolysis creates chlorine to sanitize
your pool using the salt molecules (NaCL) in your water. A small electric charge is
applied across a set of titanium plates inside the Electrolytic Cell. This produces
Sodium Hypochlorite (NaOCl). In water, Sodium Hypochlorite dissociates into
sodium (NA+) and hypochlorite (OCl-) ions.
4.1.2 It is the hypochlorite ions that form with the hydrogen (H+) ions (from the water) to
form hypochlorous acid (HOCl), which is the active agent that destroys bacteria and
algae, and oxidizes organic matter. This form of chlorine works quickly in the pipe,
leaving only a mild residual in the pool.
5.0 WATER CHEMISTRY
5.1 WARNING: Prior to turning on your CPSC Series Chlorine
Generator for the first time (including reopening your pool for the
new pool season) your water chemistry must be balanced
according to the following guidelines.
